Lignite Coal Based Activated Carbon May 09 2013
The carbon made from lignite tend to have a large pore diameter with a higher total pore volume (higher molasses number) that makes better suited for the removal of large color body molecules (removal of large molecular weight from chemical compound) from liquids and the removal of sulphur (Hydrogen Sulfide) from vapors. The carbon gives you greater adsorption capacity, high ignition temperature, lower iodine number plus lower density. Lignite based activated carbon is macroporous. It has 20% more total pore volume than bituminous based coal carbon.
325 mesh powdered activated carbon used in a purification of water and flue gas emission streams. The Bromine treatment PAC has been proven to be highly effective for the removal of mercury at coal fire power generation. Its open pore structure and fine partice size permit rapid adsorption, which is critical for high performance in flue gas streams where contact times are short less than 2 seconds.
Coal based activated carbon May 09 2013
Coal based activated carbon originates from coal that has undergone a steam activation process. During activation,millions of pores are created on the surface of the carbon, increasing the total surface area. Coal based carbon has mainly meso-pores and macro-pores and due to its unique distribution of pore diameter, coal based activated carbon is very popular in gas phase purification, potable water purification, wastewater purification and aquarium/pond water purification applications.
